Frequently asked questions

What is TOML good for?

TOML is excellent for configuration files. It's more readable than JSON and less ambiguous than YAML, used in Cargo, pyproject.toml, and more.

How are JSON structures converted?

Objects become TOML tables, nested objects become table sections, and arrays are preserved with TOML array syntax.

Can all JSON convert to TOML?

Most JSON converts cleanly. Very deep nesting or special structures may need adjustment. TOML prefers flat, clear structure.
